FIELD

The disclosure relates to the Internet field, and in particular, to an information display method and apparatus, an electronic device, and a computer storage medium.

BACKGROUND

With the development of computer technologies and graphics and image technologies, video games emerge. The video game refers to a game using a device (or referred to as a game terminal) fitted with electronic components as a running platform. Different from conventional games, which need physical game items such as chess pieces and playing cards, the video game is a game mode of interacting by controlling game terminals.

In the Internet age, video games have developed into online games. Playing online games has become one of the most popular ways of leisure and entertainment. The online games have a powerful interpersonal communication platform, and users obtain plenty of virtual reality experience in games, which was not available in the conventional games. A player (or referred to as a game user) may play a virtual role in a game interface of a game terminal, to play with other virtual roles in the game.

However, in the related art online racing games, only a track that a player has already traveled is displayed in a vehicle driving process of the player. As a result, less information is displayed and user experience is deteriorated.

FIG. 1 is a schematic diagram of a hardware environment of an information display method according to an embodiment of the disclosure. Referring to FIG. 1 , in some embodiments, the information display method provided in an example embodiment of the disclosure is applicable to the hardware environment including a terminal 101 and a server 103 shown in FIG. 1 . As shown in FIG. 1 , the server 103 is connected to the terminal 101 through a network, and may provide a service (such as a game service or an application service) for the terminal or a client installed on the terminal. A database 105 may be set up on the server or an independent database 105 may be set up independently of the server 103, and the database 105 provides a data storage service for the server 103. The network includes, but is not limited to, a wide area network, a metropolitan area network, or a local area network. The terminal 101 includes, but is not limited to, a PC, a mobile phone, a tablet computer, and the like.

The information display method in an example embodiment of the disclosure may be performed by the terminal 101, or may be performed by the terminal 101 and the server 103 in cooperation. In some embodiments, the terminal 101 has a client installed thereon and performs the information display method in an example embodiment of the disclosure by using the client.

In some embodiments, the information display method provided in an example embodiment of the disclosure includes the following operations.

S1. A terminal obtains a motion status of a target object at a current moment in a virtual scene and a first operation for controlling the target object to move in the virtual scene.

During an actual implementation, the target object may be any object in the virtual scene, for example, a vehicle object, an animal object, and a cartoon character object. The target object may be in a moving state (that is, being in movement).

The first operation is used for controlling the target object to move in the virtual scene, for example, controlling the target object to go forward, go backward, turn around, and speed up along a target route in the virtual scene.

S2. Predict a first moving track of the target object within a period of time after the current moment with reference to the motion status of the target object at the current moment and the first operation.

The first moving track includes a moving route of the target object within a period of time after the current moment.

S3. Display the first moving track and a second moving track.

In some embodiments, the second moving track is a moving track of the target object before the current moment, and a position at which the first moving track meets the second moving track is a position of the target object at the current moment.

Next, the information display method provided in an example embodiment of the disclosure is described by using an example in which the target object is a target vehicle in the virtual scene. FIG. 2 is a flowchart of an information display method according to an example embodiment of the disclosure. As shown in FIG. 2 , the method may include the following operations S202, S204, S206.

Operation S202. A terminal obtains a motion status of a target vehicle at a current moment in a virtual scene and a first operation for controlling the target vehicle to move in the virtual scene.

The virtual scene may be displayed in a client, and is a scene that is outputted by using a device and that is different from the real world. Visual perception of the virtual scene may be formed with the aid of naked eyes or devices, for example, by using two-dimensional images outputted by using a display screen or three-dimensional images outputted by using a three-dimensional display technology such as a three-dimensional projection, virtual reality, or augmented reality technology. In addition, a variety of perception simulating the real world such as auditory perception, tactile perception, olfactory perception, and motion perception may be further formed by using a variety of possible hardware. During an actual application, the virtual scene may be a game scene.

The first operation is an operation that is detected on the client at the current moment and used for controlling the target vehicle to move in the virtual scene.

The client is a client provided after a target application is installed on the terminal. The virtual scene is a social or game virtual scene or the like provided by the target application (such as a social application or a game application). The client provides an interface for a user to interact with a vehicle in the virtual scene, so that the user controls the vehicle. For example, control buttons are displayed on the client, and the user may control the vehicle by manipulating (e.g., tapping/clicking) these control buttons (such as buttons for controlling the first operation detected on the client at the current moment and a second operation at a time later than the current moment).

The motion status may include at least one of a moving velocity, a moving direction, and an external force to the target vehicle. The first operation is a user operation, for example, an acceleration operation or a deceleration operation.

Operation S204. The terminal determines a first moving track of the target vehicle within a period of time after the current moment according to the motion status and the first operation.

The terminal predicts the first moving track of the target vehicle after the current moment according to the motion status and the first operation. That is, the terminal estimates a moving track of the target vehicle in a future period of time (for example, 10 seconds) according to the motion status and the first operation. The moving track may include a moving route and a moving direction.

Operation S206. The terminal displays the first moving track and a second moving track on the client, the second moving track being a moving track of the target vehicle before the current moment, and a position at which the first moving track meets the second moving track being a position of the target vehicle at the current moment.

Through the foregoing operation S202 to operation S206, the first moving track may be displayed at the same time as the second moving track. That is, a predicted traveling track of the vehicle in a future period of time is displayed at the same time as a track that the vehicle has traveled, so that more relevant information is displayed in a virtual scene. In addition, it helps a user to control the target vehicle more accurately and improves user experience.

An example embodiment of the disclosure provides a solution to visually present comprehensive game information and a solution to comprehensively determine a traveling direction according to factors such as power, steering, and inertial resistance, present travel information in a game in real time, and provide feedbacks on inertia and presentation manners during interactive presentation of the game and a scene. The technical solutions of an example embodiment of the disclosure are described below in detail with reference to operation S204 to operation S206.

In the technical solution provided in operation S204, the terminal determines a first moving track of the target vehicle within a period of time after the current moment according to the motion status and the first operation.

In the foregoing embodiment, the determining a first moving track of the target vehicle within a period of time after the current moment according to the motion status and the first operation may be implemented by using the following operation S2042 to operation S2046.

Operation S2042. Determine a first velocity v1 of the target vehicle at a first moment t1 by using a power model.

The power model is configured to describe a relationship between an external force to the target vehicle at a second moment t2, a second velocity v2 of the target vehicle at the second moment t2, traction of the target vehicle at the second moment t2, and the first velocity of the target vehicle at the first moment t1.

The second moment is a moment before the first moment, and the motion status includes the external force to the target vehicle at the second moment and the second velocity of the target vehicle at the second moment.

The traction of the target vehicle at the second moment is determined according to the first operation.

In some embodiments, the determining the first velocity of the target vehicle at the first moment by using the power model includes: when the external force includes friction of the target vehicle at the second moment, determining a first velocity corresponding to the friction of the target vehicle at the first moment, based on the second velocity and the traction of the target vehicle at the second moment by using the power model. That is, when the external force to the target vehicle at the second moment includes the friction of the target vehicle at the second moment, the power model is configured to describe a relationship between the friction, the second velocity, the traction of the target vehicle at the second moment, and the first velocity. Accordingly, the first velocity may be determined by using the relationship between the friction, the second velocity, the traction of the target vehicle at the second moment, and the first velocity. In an example embodiment, a resultant force F of the external force, that includes the friction, and the traction may be calculated, to obtain acceleration a=F/m, m being the mass of the target vehicle, and v1=v2+(t1−t2)×a, wherein v1 is the first velocity and v2 is the second velocity.

In some embodiments, the determining the first velocity of the target vehicle by using the power model includes: when the external force includes a rebound force of the target vehicle in a collision at the second moment, determining the first velocity corresponding to the rebound force of the target vehicle at the second moment based on the second velocity and the traction of the target vehicle at the second moment by using the power model. That is, when the external force to the target vehicle at the second moment includes a rebound force of the target vehicle in a collision at the second moment, the power model is configured to describe a relationship between the rebound force, the second velocity, the traction of the target vehicle at the second moment, and the first velocity. Accordingly, the first velocity may be determined by using the relationship between the rebound force, the second velocity, the traction of the target vehicle at the second moment, and the first velocity. In an example embodiment, a resultant force F of the external force, that includes the rebound force and the traction may be calculated, to obtain acceleration a=F/m, m being the mass of the target vehicle, and v1=v2+(t1−t2)×a.

A direction of the acceleration a is a direction to which the acceleration is applied at the second moment. Acceleration at the first moment may be calculated by using a similar method (that is, using the resultant force F), and a direction of the calculated acceleration is applied at the first moment. As described in detail below, the direction of the acceleration may be represented with an arrow symbol on a game interface.

Operation S2044. Determine a track point of the target vehicle at the second moment according to the first velocity and the second velocity of the target vehicle.

For example, when a track point at the first moment t1 is known, a distance that the target vehicle travels from the first moment t1 to the second moment t2 may be calculated by using integral or another manner, and then the track point of the target vehicle at the second moment t2 may be determined.

Operation S2046. Fit at least two track points within the period of time to obtain the first moving track.

All track points may be fitted by using a fitting formula, and if the first moving track cannot be completely represented by using a track of a formula, the first moving track may be represented in a form of a plurality of track segments. The process of fitting may be understood as a process of substituting values of known track points into the fitting formula to obtain values of unknown parameters in the fitting formula.

In the technical solution provided in operation S2046, the terminal displays the first moving track and a second moving track on the client, the second moving track being a moving track of the target vehicle before the current moment, and a position at which the first moving track meets the second moving track being a position of the target vehicle at the current moment.

In some embodiments, the first moving track and the second moving track may be displayed in the following manner:

-   -   displaying the first moving track in a first display manner and         the second moving track in a second display manner on the         client. The first display manner is different from the second         display manner. The display manners include, but are not limited         to, different track colors, different shapes or different colors         of track fillers, and different track shapes.

In some embodiments, for the first moving track, a presentation manner is not limited to a special effect of an arrow, and further includes other presentation manners that may present vector information such as a direction and/or a length by using relevant information.

In some embodiments, if there is no obstacle in the estimated moving track (that is, the first moving track) of the target vehicle, the first moving track is a complete track. If there is an obstacle in the estimated moving track of the target vehicle, the first moving track includes a plurality of track segments. In this case, the displaying the first moving track in a first display manner on the client includes: displaying a first track segment and a second track segment in the first display manner on the client. The first moving track includes the first track segment and the second track segment. The first track segment uses the position of the target vehicle at the current moment as a start position, and the first track segment is a moving track generated when the target vehicle moves according to the motion status. The second track segment uses an end position of the first track segment as a start position, and the second track segment is a moving track generated when the target vehicle moves according to the motion status and collides with an obstacle.

In some embodiments, in the process of displaying the first moving track and the second moving track on the client, when a second operation is detected on the client, that is, when there is a new operation of the user, a third moving track and a fourth moving track according to the new operation are displayed on the client. The third moving track is a moving track of the target vehicle after the second operation (or new operation) is detected, and the fourth moving track is a moving track of the target vehicle before the second operation is detected. The third moving track is determined in the same manner as the first moving track, and details are not repeated herein. The second operation is different from the first operation detected on the client at the current moment.

Based on the technical solutions of the disclosure, a result of comprehensive forces to a unit operated by a user and a prompt of interaction with a scene may be presented in an intuitive display form, to prompt the user to avoid subsequent adverse consequences in advance.

The information display method provided in an example embodiment of the disclosure is described below in detail by using an example in which the technical solution of an example embodiment of the disclosure is applied to a game, that is, the virtual scene is a game scene.

FIG. 3 is a schematic diagram of an example of a game interface. As shown in FIG. 3 , in racing games, for example, games such as QQ Speed, and Together with Speed, route prediction and cognition are implemented by using an orientation of a vehicle head. For example, reference number 31 in FIG. 3 represents a vehicle head part of a vehicle, and a user predicts a heading route by using an orientation of the vehicle head. However, go-kart inertia cannot reflect an actual heading direction of the vehicle by using this method. Because the inertia force is relatively simple, it is more feasible to present a traveling direction by using the orientation of the vehicle head. However, when friction and the like are considered, the orientation of the vehicle head cannot reflect the actual heading direction of the vehicle.

FIG. 4 is a schematic diagram of another example of a game interface. In a go-kart game shown in FIG. 4 , because of the inertia and the friction, a traveling direction of a vehicle cannot be presented intuitively in the foregoing presentation manner in FIG. 3 . A direction indicated by an arrow of reference number 41 in FIG. 4 is a current vehicle head direction, but the direction is not the traveling direction of the vehicle. If a heading direction (or traveling direction) is perceived by using a reverse extension line of a wheel, for example, a direction indicated by an arrow of reference number 42 in FIG. 4 is a direction of the reverse extension line of the wheel, the current heading direction of the vehicle may be obtained by using the direction. However, it is relatively difficult for a beginner user to perceive an actual meaning of this presentation manner.

Based on the above problems, the information display method in an example embodiment of the disclosure is provided. A result (including a direction and a size) of comprehensive forces to a unit operated by a user and a prompt of interaction with a scene may be presented in an intuitive display form, to prompt the user to avoid adverse consequences in advance and to perform subsequent operations.

FIGS. 5 and 6 are schematic diagrams of a game interface according to example embodiments of the disclosure. As shown in FIG. 5 , an extension line (for example, an arrow that is before a vehicle and that is indicated by reference number 51 in FIG. 5 ) of the vehicle operated by the user indicates a traveling direction of the vehicle, and along with operations on a power model, the indication line changes in real time to display a subsequent traveling track. As shown in FIG. 6 , when a vehicle is going to collide, a predicted track line is also presented according to a rebound route. As shown by reference number 61 in FIG. 6 , when the vehicle is going to collide, the predicted track line changes (to the track line indicated by the reference number 61) and is displayed according to the rebound route.

Based on the technical solution of an example embodiment of the disclosure, a prediction is performed by using a power model of a vehicle in real time according to a current vehicle traveling status and a user operation, and a traveling route of the vehicle within a fixed duration (for example, 1 second) is provided with special effects. FIG. 7 is a flowchart of an information display method according to an example embodiment of the disclosure. An implementation is shown in FIG. 7 and includes the following operations.

Operation S701. Detect an input operation (for example, the first operation), and predict a quantity n of frames.

Operation S702. Update power model data when the user operation does not change.

Operation S703. Determine whether n updates have been completed, and perform operation S704 if the n updates have been completed or perform operation S702 when the n updates have not been completed.

Operation S704. Process position information and maintain relative stability with the vehicle.

Operation S705. Generate visual representation (e.g., an arrow) according to position data of the n frames.

Based on the foregoing embodiment of the disclosure, the power model in the game application monitors the user operation in real time, and updates a predicted route of the track and a special effect mark for presentation when there is any input operation of the user or the vehicle collides during racing.

According to an example embodiment of the disclosure, power, a steering operation, and a drift inertia decay may be calculated to obtain a final result, which is a vector result based on a velocity and a heading direction. FIG. 8 is a schematic diagram of a vehicle state according to an example embodiment of the disclosure. As shown in FIG. 8 , f is friction to a vehicle during turning, which is opposite to a heading direction, F is an actual heading direction, and v is vehicle power. F depends on a result of comprehensive calculation based on f and v. FIG. 9 is a schematic diagram of an example of a game interface. As shown by reference number 91 in FIG. 9 , a traveling track of a vehicle within a period of time may be determined by using a function of a current force and the period of time. However, the traveling track is not visible to the user in the related art. This may make it difficult for the user to understand inertia of the vehicle.

According to an example embodiment of the disclosure, the vector may be presented in a form of a special effect, and a center-of-gravity position of the unit (e.g., vehicle) operated by the user is connected to an end point position based on the result of the foregoing force (that is, friction and vehicle power) after x time units by using a special effect. Through the length, angle, and radian of the special effect, the user may intuitively feel the predicted position after the x time units. A heading force direction is current acceleration of a traveling route, and an arc-shaped traveling route may be obtained through recursive processing.

FIG. 10 is a schematic diagram of a game interface according to an example embodiment of the disclosure. As shown in FIG. 10 , any operation (for example, the foregoing second operation) of the user that may affect a traveling result may be fed back in real time in the game. For example, if the power applied to the vehicle increases, a displayed special effect stretches (as the velocity increases, a traveling track in the same period of time is longer), and a force angle (that is, the traveling direction) changes. In some embodiments, the first moving track is displayed in a target color when there is an obstacle in the first moving track, the target color being different from a color when there is no obstacle in the first moving track. In some embodiments, under normal driving conditions, the predicted route is displayed in green. For example, an arrow indicated by reference number 11 in FIG. 10 is a predicted route and is green. If a collision is to occur, the predicted route (e.g., the arrow indicated by reference number 11) changes to red to alarm, and a traveling route caused by a collision result is displayed according to the collision result.

Based on the foregoing embodiment of the disclosure, a traveling track and a final force condition of the vehicle during driving may be intuitively presented. By intuitively displaying a power model and a traveling trend of the vehicle, the user may easily understand factors that determine the traveling direction (e.g., power, steering, and inertial resistance), which makes it easy for the user to control the vehicle.

For ease of description, the foregoing method embodiments are stated as a combination of a series of actions. However, a person skilled in the art is to know that an example embodiment of the disclosure is not limited to the described action sequence, because according to an example embodiment of the disclosure, some operations may be performed in another sequence or simultaneously. In addition, a person skilled in the art is to also understand that the embodiments described in this specification are all example embodiments; and therefore, an action and a module involved are not necessarily mandatory in the embodiments of the disclosure.

According to the descriptions in the foregoing implementations, a person skilled in the art would clearly understand that the method according to the foregoing embodiment may be implemented by using software and a commodity hardware platform or by using hardware. Based on such understanding, the technical solutions of the embodiments of the disclosure or some contributing to the related art may be implemented in a form of a software product. The computer software product is stored in a storage medium, such as a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc) and includes several instructions for instructing a terminal device (which may be a mobile phone, a computer, a server, a network device, or the like) to perform the methods described in the embodiments of the disclosure.

An embodiment of the disclosure further provides an information display apparatus for performing the information display method. In some embodiments, the information display apparatus provided in an example embodiment of the disclosure includes:

-   -   an obtaining unit, configured to obtain a motion status of a         target object at a current moment in a virtual scene and a first         operation for controlling the target object to move in the         virtual scene;     -   a determining unit, configured to predict a first moving track         of the target object within a period of time after the current         moment with reference to the motion status of the target object         at the current moment and the first operation,     -   the first moving track including a moving route of the target         object within a period of time after the current moment; and     -   a display unit, configured to display the first moving track and         a second moving track, the second moving track being a moving         track of the target object before the current moment, and a         position at which the first moving track meets the second moving         track being a position of the target object at the current         moment.

An embodiment of the disclosure further provides an information display apparatus for performing the information display method. FIG. 11 is a schematic diagram of an information display apparatus according to an example embodiment of the disclosure. As shown in FIG. 11 , the apparatus may include: an obtaining unit 1101, a determining unit 1103, and a display unit 1105.

The obtaining unit 1101 is configured to obtain a motion status of a target vehicle at a current moment in a virtual scene and a first operation for controlling the target vehicle to move in the virtual scene.

The client is a client provided after a target application is installed on the terminal. The virtual scene is a social or game virtual scene or the like provided by the target application (such as a social application or a game application). The client provides an interface for a user to interact with a vehicle in the virtual scene, so that the user controls the vehicle. For example, control buttons are displayed on the client, and the user may control the vehicle by manipulating (e.g., tapping/clicking) these control buttons (such as buttons for controlling the first operation and a second operation).

The motion status may be at least one of a moving velocity, a moving direction, and an external force to the target vehicle. The first operation is a user operation, for example, an acceleration operation or a deceleration operation.

The determining unit 1103 is configured to combine the motion status and the first operation to predict a first moving track of the target vehicle within a period of time after the current moment, the first moving track including a moving route and a moving direction of the target vehicle within a period of time after the current moment.
